The estates and lordships were passed by strict entail of the 12th Earl of Glencairn to the "heirs male of her own body" of his eldest daughter, Lady Margaret Cunningham, wife of Nicol Graham of Gartmore and to their line should his male heir line fail, which it did upon the death of the 15th Earl of Glencairn in 1796. Sir John petitioned the Lord Lyon, King of Arms, for recognition as Chief of the Name and Arms of Cunningham in March 2010 and was recognised as such by the Lyon's interlocutor of 18 December 2013 as Cunninghame of that Ilk. He is, therefore, the first Chief of the House of Cunninghame in over 200 years. There is no heir to the baronetcy of Corsehill, though his chiefship may pass to and through the female line.
